FN-9149: Add PostgreSQL timeout-boundary diagnostics
Instrument the opt-in PostgreSQL test harness to attribute loaded-lane timeout failures without changing default behavior.
- Add bounded setup, body, and teardown watchdog probes with host, cluster, and template evidence.
- Wire observer records into the harness and loaded-failure census with explicit suppression and attribution handling.
- Cover observer inertness, boundary behavior, and census joins while documenting the 27-worker campaign findings.
